PAPER-CUTTER.

To all whom it may concern:

Be it known that I, CORNELIUS C. HAST- INGS, a citizen of the United States of America, residing at Springfield, 1n the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Paper-Cutters, of which the following is a specification.

This invention relates to an improvement in paper cutters.

Machines of this class are used for many different kinds of work.

The object of this invention is to improve the type of machine referred to and render it more convenient when in use. This ob ect is attained by the structure herein set forth which provides means whereby, after the knife has been brought down, it will return immediately to an elevated position when released.

Other objects will appear in the following detailed description and annexed claims.

In the drawing forming part of this application,-Figure l is a plan view of a paper cutter embodying my inventlon. Fig. 2 is a side view of the same.

The paper cutter comprises the usual table portion 0 at one end of which the knife a 1s pivoted in the usual manner. A spring 6, shown in Fig. 1, keeps the knife a against the edge of a cutter bar on the board.

Referring to Fig. 1, cards or paper of comparatively small area can be cut at the end 00 of the cutter-board, while cards of comparatively large area can be out only when the knife (4 is raised far enough to permit their insertion under the knife toward the part y of the cutter-board. Cards or stock of other dimensions between the large and small sizes will be cut by raising the knife edge above the cutter-board proportionally between the points at and 2 In order to provide means whereby, after the knife has been brought down it will return immediately to an elevated position when released, the following mechanism is provided: An arm 7 is fixed to the bolt (Z on which the knife is secured, and to the end of this arm a flexible connection 9 is fastened. The other end of the connection 9 is fastened to a coiled spring h. A lever b is pivoted at Z and when swung carries one end of the spring h, to which it is connected. A notched plate is on the side of the frame Specification of Letters Patent.

serves to keep the outer end of the lever b in any one of several adjusting positions. It is clear from the foregoing that the spring it will determine the position of the knife a. Accordingly, as the lever b is placed in one notch of the plate Kc, or another, the spring it is put under more or less tension.

The operation is as follows :If it is desired to cut stock to the limit of the machines capacity, the lever Z) is fixed in the left-hand slot of the plate k thus putting the spring it under its greatest tension and raising the knife-blade a so that the stock can enter under the knife adjacent the portion 3 of the cutter-board. The paper or other stock is then cut in the usual manner. WVhen the handle 25 is released, the tension of the spring it immediately raises the knife for another cutting operation. In a similar manner, if comparatively small stock is to be out, then the lever b is placed in the righthand notch of the plate k. The tension put on the spring will in this case cause the knife to take up the position shown in Fig. 2.

For stock of a size between the smallest and largest sizes the lever b is placed in a suitable one of the intermediate slots of the plate 70 to normally raise and keep the knife at a desired point.

By the use of the apparatus described, a paper cutter of large capacity can be conveniently adapted for operating on all sizes of stock.

Applicant does not limit his invention to the specific form shown for it can be embodied in various forms.

What I claim, is

1. A cutter comprising a frame, a knife pivoted at one side thereof to cooperate with another side thereof for cutting operations, whereby as the knife is turned on its pivot smaller or larger stock can enter under the knife to be cut, and means for elevating said knife to accommodate different sized stock comprising a resilient means to turn and elevate the knife in one direction, and lever setting devices including a rack secured to the frame to adjust said means to accurately determine the position the knife is to be elevated in accordance with the stock to be cut.

2. A cutter comprising a frame, a shaft rotatably mounted therein, a knife fixed thereon, an arm also fixed thereon. a lever pivoted. on the frame, a flexible spring connection between one. end of the lever and the springwill raise the knife for the pursaid arm whereby When said lever is turned pose described.

to put the spring under tension, the arm will turn the shaft and elevate the knife, and CORNELIUS HASTINGS means for setting the lever in one-pf sev= Witnesses:
